Application filed August 12, 1904. Serial No. 220,472.

-in Means of Suspending Incandescent-Lamp Mantles, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to `make and use the same.

The invention relates to means of suspending incandescent-lamp mantles.

One of the objects thereof is to provide a means of suspension for objects of the above type whereby they are protected from theinjurious effects of the vibration of the structure in which they are mounted.

Another object is to provide means of the above nature which are easily replaced and substantially unaifected by heat.

A broad object is to provide a suspension for lamp-mantles peculiarly adapted for use in lighting cars, boats, factories, and similar places in which jarring and vibration are unavoidable and often severe.

Other objects will'be in part obvious and in part pointed out hereinafter.

The invention accordingly consists in the features of construction, combination of elements, and arrangement of parts, which will be exemplilied in the device herein described and the scope of the application of which will be indicated in the following claims.

In the accompanying drawings, wherein are illustrated several of various possible embodiments of my invention, Figure l is a sectional elevation of a lamp-mantle and means for suspending the same. Fig. 2 is a similar View of a slightly different embodiment of my invention. Fig. 3 is a similar view of another embodiment thereof. Fig. 4 is a similar view of another form.

Similar reference characters refer to similar parts throughout the several views.

The invention proposes, broadly, a mantle suspension in which the mantle is mounted upon its support by means of a resilient and preferably incomhustible material and in such manner that the connection between the two may be readily made or broken manually, but is not likely to be broken accidentally while in use. v f

Referring first to the embodiment of the invention shown in Fig. l, a supporting member or conduit for conveying gas to the burner is shown at 1. The lower end of this member is preferably provided with an outturned flange or shoulder 2 for a purpose hereinafter described. Mantle 3 is mounted upon a spool or ring 4, preferably formed of porcelain or similar material, and is secured to the same above an outwardly-projecting shoulder 5, preferably by means of an asbestos cord 6. The internal diameter of spool 4 is considerably larger than the lower end of support l and is adapted to surround the same, as shown in the drawings. Ooiled within spool 4c is a resilient packing 7,which is preferably formed of a refractory fibrous material, as asbestos wicking. This wicking may be secured to the ring in any desired manner, as by the use of, water-glass or a similar heat-resisting cement and is of such size as normally to leave an inner opening slightly smaller in diameter than the outside of the lower end of support l. The outer face ofshoulder 2 is preferably beveled downwardly and inwardly, and it will accordingly be seen that the parts may be assembled by forcing the spool onto its support until the desired adjustment is attained, when the shoulder 2 will prevent disengagement thereof. If desired, an inwardlyextending flange 8 may be provided on the upper end of the spool, which will aid in holding the packing in place. The joint or connection between the support and spool may also be made more stable by means of a metal cap 9, spun about the end of support l, following the upward bevel of shoulder 2 and extending beyond the same in a series of serrations or teeth l0. The connection between the cap and the support may be made more stable by bending down alternate teeth over the top face of shoulder 2, as shown in Fig. l, thus assisting in locking thev cap in position. The bevel of this cap being the same as that of the shoulder will permit the ready mounting of the spool upon the support, but tend to resist even more strongly than the shoulder any disengagement thereof. lf it is desired to remove the spool from the support for the purpose of supplying a fresh mantle or otherwise, a comparatively slight manual pressure will break the joint between the two.

IOO

The normal assembled position of parts is such that the lower end of support 1 is out of contact with spool 4, thus permitting a slight relative movement of the two parts without contact between the same.

It will thus be seen that I have provided a means of suspension for members of the nature of incandescent-lamp mantles in which the vibration and jars transmitted to the supporting means are cushioned and the mantle thus protected from any undesirable shock.

The several parts used in embodying my invention are simple, inexpensive, and the same may easily be placed in connection with lighting systems at present in use with slight alterations. The resilient suspending means are simple and easily adjusted and are unaffected by the heat to which they may be subjected. rIhe joint, moreover, between the supporting member and that part upon which the mantle is mounted may be rendered substantially gas-tight by reason of the fibrous qualityof the packingwithoutinterferingwith the resiliency of the mounting. It will be noted that although in my means of suspension the mantle will be mounted with any desired degree of resiliency it is nevertheless unnecessary to provide a considerable range of movement of the same, and the consequent objectionable feature of a moving source of light is avoided.

In the embodiment shown in Fig. 2 of the drawings the supporting member 11 extends entirely through spool 12 and forms the iamenozzle of the burner, the spool being enlarged with reference to the supporting member, so as to permit such position. by the term name-nozzle is meant such a member as is adapted to convey gas or similar matter and discharge the same in such manner as to permit the efficient burning` of the same at the point of discharge, whereas gas-nozzle is used to designate a part adapted to convey and discharge gas. 'lhis embodiment differs from that shown in Fig. 1 also in the omission of the inwardly-extending flange on the upper end of the spool.

In Fig. 3 is shown another embodiment which is similar to that shown in Fig. 1, some of the parts being reverse in position with reference to that figure. Support 13 is extended downwardly and is preferably provided with slight ridges or shoulders 14 and 15. Between these shoulders is secured a resilient sustaining means 16, which may be of asbestos packing, as in the above embodiment. This packing means may be wound tightly about support 13 between shoulders 14 and 15 or may be secured to the same in any other desired manner. The spool or ring 17 is suspended from packing 16 by means of a metal ring or cap 18, spun thereon and 'held in place bymeans of a flange or shoulder formed on the spool, if desired.

The method of assembling the partsof the.

last-described embodiment 'of my invention is substantially the same as that first described, the spool being forced upon packing about member 13 in a manner which should be apparent from the drawings and is secured in this assembled position by means of the teeth of cap 18.

In Fig. 4 is shown a construction similar to that shown in Fig. 1, the principal change lying in the elimination of a metal cap or crown. In this construction the shoulder 20 would be alone relied upon to form the slip-joint between the support and the spool, and it may accordingly be of somewhat greater width. if found desirable.

All of the embodiments of my invention may, if desired, be surrounded by a translucent shade or globe in a well-known manner, and the constructions above described are peculiarly adapted to withstand the shock attendant upon opening' or closing or the removal and replacing of such member.

Although the several embodiments herein shown are represented as extending downwardly and the invention is peculiarly adapted for constructions in which the mantle is suspended from its upper portion, nevertheless the mantle may be mounted in any desired direction. In other words, with the construction indicated it is immaterial to what angle the gas-conduit is turned. and while the form in which the mantle is suspended vertically from the conduitis preferred the mantle will burn even although its position is reversed so that it extends upwardly from the support. It will also be obvious that it is immaterial whether the mantle is directly connected to the gas-conduit or whether it is connected to an auxiliary support, so long as it is properly positioned with reference to the conduit. Further modifications, as well as obvious.

As many changes could be made in the above construction and many apparently widely different embodiments of my inventioncould be made without departing from the scope thereof, I intend that all matter contained in the above description andl shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

Certain features broadly shown and described in this application are shown, described, and claimedin my copending application, filed of even date herewith, Serial No. 220,473.
